Question

if 25% of a number is subtracted from a second number the second number reduces to its 5 vi what is the ratio of the first number to the second number​

Answer 1

Answer:

The ratio of the first number to the second number is 16:5

Step-by-step explanation:

I am assuming that the problem reads as "..............the second number reduces to its fifth.........."

Let "x" and "y" be the first and second number, respectively.

ATQ,

y - 25% of x = 1/5 of y

=> y - x/4 = y/5

=> x/4 = y - y/5

=> x/4 = 4y/5

=> 5x = 16y ..........on cross multiplying

=> x/y = 16/5

The two numbers are in the ratio 16:5
